Assigner: VulnCheck

Description
Ghost from 0.7.2 before 6.64.0 contains an information disclosure vulnerability in the Admin API that allows staff-level users to determine the relative ordering of other staff users' password hashes. Authenticated staff users can query the Admin API to infer hash ordering, though this does not directly reveal hashes or enable practical password recovery.

Executive Summary

This vulnerability in Ghost (versions 0.7.2 to 6.64.0) allows staff-level users to determine the relative ordering of other staff users' password hashes via the Admin API. It does not expose the hashes directly or enable password recovery, but it reveals hash sequence information.

Detection Guidance

To detect this vulnerability, check the Ghost version installed on your system. If it is between 0.7.2 and 6.63.0, the system is vulnerable. Use commands like 'ghost version' or check the Docker image tag if using a containerized setup.

Impact Analysis

The impact is limited. It only allows staff users to infer hash ordering, not recover passwords. The attack requires low privileges and high complexity, making practical exploitation unlikely. Confidentiality is slightly impacted as hash order may hint at password strength or patterns.

Compliance Impact

This vulnerability has minimal compliance impact. It does not directly expose sensitive data or violate major regulations like GDPR or HIPAA. The low severity and limited confidentiality impact reduce regulatory risk.

Mitigation Strategies

Update Ghost to version 6.64.0 or later immediately. For Docker users, pull the latest official Ghost image. Ghost-CLI users should follow the official update documentation to patch the vulnerability.
